Update (5:30 ET): A Facebook spokesperson responded to Quartz, saying: “For a brief period today, a message meant for memorialized profiles was mistakenly posted to other accounts. This was a terrible error that we have now fixed. We are very sorry that this happened and we worked as quickly as possible to fix it.”

Facebook didn’t comment further on the what caused the glitch, and one wonders whether, in his attempt to rid the entire world of disease, CEO Mark Zuckerberg felt it necessary to kill us all.

Roughly three months ago, as part of a Facebook hackathon that Mark Zuckerberg attended, a group pitched him an improved way to memorialize those that have died. It’s entirely possible that this new memorial feature could be the result of an attempt implement this or a similar idea.

It appears that people that have actually passed away and still have Facebook pages are not experiencing the current glitch. Right now, when a family wishes to keep the page alive as a way for loved ones that have passed away, Facebook just adds a line above their name saying “Remembering.”

The glitch only lasted a short while, and it appears that Facebook has returned its users to the world of the living.
